Clients should ALWAYS be happy with your service because it reflects YOU. If your clients aren't smiling and raving about your business, you need to get to the root of the issue and ask - are they genuine clients?
A genuine client...
understands you're not perfect or the least expensive option for their needs
accepts what you offer with the highest value and integrity
trusts your judgment, skillset, experience, and motives
acknowledges your limitations and doesn't terminate business because of them
reciprocates your loyalty with glowing praise and heartfelt referrals
Remember - one genuine client is worth more than a hundred ingenuine clients.
